I have some sort of Bingo Wheel and want to make animation of Balls rotating in it. Balls are supposed to bounce in wheel, and those, I will call them "Arms" are constantly rotating so I want balls to interact with them, and with edges of spheres.
I added rigid body > passive > collision (mesh) to sphere, and duplicated it and did same to that new sphere because balls were going outside of sphere if there is only one. Also, added rigid body > passive > collision to those hands, to make them interact with balls. But somehow I feel something is missing since they are always moving in same direction.
